I made a quick outline of my installation. I recommend you verify all the connection points before you begin because I could have made a mistake in my markups. I don't want to be responsible. Installation took a couple hours but I took my time and checked back to the schematics quite often. The longest part of the installation was removing the side because I didn't want to damage any of the clips.

Notes:
1. I used the loudest piezo electric buzzer I could find at radio shack instead of connecting to the lights. I felt as I walk away I wanted to hear the doors lock instead of having to turn around and watch to make sure the lights blink. The buzzer isn't as loud as I hoped. I'll probably add a relay and connect to the lights as well as keep the buzzer. I could have probably connected to the car horn but I didn't want to run wires to the front, and think that a car horn beeping for locking and unlocking is too loud and annoying.
2. I mounted one antenna near the outside air vent because there is no metal blocking the signal path, I figured it would give me decent response from the back hatch as well as approaching the car from the driver side. Its tie wrapped to a piece of plastic that I screwed onto the chassis. I could have found something more professional to mount it to, but I used what was handy.
3. I mounted the other antenna in the middle of the B pillar. I figure this one will pick up the keys when they are in the car as well as when I leave. I left the passenger side alone because rarely if ever will someone with a key be on that side of the car. You could buy the optional 3rd antenna if it is a concern.
4. I screwed the module on to the chassis but probably should have moved it more toward the back so I could see the LED when the access panel to the light bulbs is opened.
My 2102T settings:
1. RF - NA
2. Door Unlock Timing = 3.5 seconds so it unlocks all doors,
a shorter setting will only unlock the drivers door
3. Door Lock timing = 3.5 seconds, I don't think it is critical.
4. Number of Antenna = 2
5. Smart Lock = 5 minutes, personal preference
6. Door Open Interlock = Off, Personal preference.
Performance:
Works well so far. The doors unlock before I reach for the door handles and
they lock when I'm about 10 feet away from the car. I'm using the smart lock
option as well as the door open interlock and they both seem to work as
advertised as well
